Sunken Concrete is Both a Safety Hazard and a Liability

That sunken concrete slab isn’t only unattractive, it’s also a trip hazard. If someone falls and gets injured, you could find yourself facing a lawsuit. So, make sure you don’t put this repair on the back burner.

We are able to lift sunken or settled concrete slabs in Pleasanton, CA including, but not limited to…

Benefits Of Concrete Lifting Via Polyurethane Foam Injection

he benefits of concrete lifting – also known as slabjacking or polyurethane foam injection – are many, including:

  • Polyurethane foam won’t add more weight to the soil. Concrete slabs often sink because the soil they’re sitting on is unable to support them. Another common method of lifting and leveling concrete called “mudjacking” uses a cement slurry to lift the slab. Because cement is heavy this adds even more weight to the soil. If the soil was having trouble supporting the concrete before, adding more weight to it isn’t going to help. Polyurethane foam, on the other hand, is ultra lightweight and able to lift up the slab without adding additional weight to the soil.
  • It’s a cost-effective solution. Concrete lifting via polyurethane foam injection doesn’t cost as much as pouring a brand new slab.
  • It’s a fast repair. Polyurethane foam injection usually only takes a few hours to complete, tops. You can also use the slab immediately after the repair is complete.
  • It doesn’t harm the environment. Polyurethane foam is an environmentally-friendly solution that won’t leach harmful chemicals into the soil.
  • Even concrete just looks good! Sunken, uneven concrete is an eyesore.

What Causes Concrete Slabs To Sink Or Become Uneven?

Concrete slabs sink and become uneven for a variety of reasons including…

Drainage problems. If the soil under and around the slab contains an excess amount of water, if can wash away the soil and leave behind voids that the slab will then sink into.

Weak soil. Some soils aren’t able to support the weight of a heavy concrete slab.

Expansive soil. Expansive soils are those that swell as they soak up water and shrink when they dry out. Over time this swelling-shrinking cycle – that’s usually seasonal – can cause uneven slabs.

Invasive tree roots. You’ve probably seen this many times in your life. Tree roots push against a slab and cause sections of it to become uneven.

What are the Different Ways to Lift a Concrete Slab?

The two “old school” methods of lifting and leveling a concrete slab were mudjacking and digging up the old slab and pouring a new one. They weren’t the best solutions though, as you will see. Today, polyurethane foam injection is the method of choice for repairing a sunken slab.

Mudjacking

Mudjacking is a procedure where small holes are drilled into the slab, and then a slurry of soil, water, and cement is injected under the slab in order to lift it back up. The problem with mudjacking is the weight of the slurry. It’s heavy because it contains cement. If the soil was already struggling to support the slab, adding even more weight to it won’t help. It will only make things worse.

Concrete Replacement

Another traditional method for repairing a sunken slab is to simply dig it up and pour a new one. This is a time-consuming fix though. It takes time for newly poured cement to dry and cure (harden). This means there’s going to be some downtime while you’re waiting to use the new slab. Also, if the soil wasn’t able to support the old slab, it won’t do any better with the new one.

Polyurethane Foam Injection

Polyurethane foam injection (also known as ‘’slabjacking’’) uses a super lightweight foam that rapidly expands as soon as it’s injected under the slab. This lifts the slab back into position. It’s a fast repair that can usually be completed in a few hours and when it’s done, you can immediately start using the slab again.

We had an amazing service experience from David and Rico of Bay Area Underpinning. David and Rico were very professional, super nice, and worked hard on leveling my floor. They arrived on time after giving me a call earlier to let me know they are on the way. They put on shoe covers to make sure my floor is protected. They patiently listened to my inputs and addressed my concerns with competence and great care. And they would not leave until all the uneven floor areas are fixed to my satisfaction. This team deserves my 5 star rating.

I recommend Bay Area Underpinning for an important reason: honesty. After careful inspection, their agent, Richard, told me the truth, which was that my crawlspace was fine, that I had no problem with moisture or settling. And then he took the time to show me why. He could have tried to sell me on doing a lot of work, but he didn't. This kind of honesty is impressive! Call Bay Area Underpinning to inspect your crawlspace. You can trust them. If they say it needs work, hire them to do it. I am almost sorry I couldn't!

When we had our 1960s home underpinned, the consultant arrived on time to give us a quote. He gave us different options for work to be done and had solutions to cutting cost on things that weren't absolutely necessary. The work was done within a week. All of the workers were professional. Something that stood out the most was the way the workers communicated with each other. They weren't your typical construction crew in this sense. They were very kind to each other and supportive of each other, even when they were in a difficult situation. This isn't common in construction. As for the cost, it was what we had expected and we don't have any complaints. Our house is level now and doesn't feel like we're drunk walking in areas that were previously sagging. There's a reason Bay Area Underpinning is #1 in the area. Would recommend, even if they aren't the cheapest- they get the job done right.
